ATOMIC_DEFINE

Intrinsic Subroutine (Generic): Defines a variable atomically.

CALL ATOMIC_DEFINE (atom, value)

atom

(Output) Must be a scalar coarray or coindexed object and of type integer with kind ATOMIC_INT_KIND or of type logical with kind ATOMIC_LOGICAL_KIND. If its kind is the same as that of value or its type is logical, it becomes defined with the value of value. Otherwise, it becomes defined with the value of INT (VALUE, ATOMIC_INT_KIND).

ATOMIC_INT_KIND and ATOMIC_LOGICAL_KIND are named constants in the intrinsic module ISO_FORTRAN_ENV.

value

(Input) Must be a scalar and of the same type as atom.

Example

Consider the following:

CALL ATOMIC_DEFINE (N [9], 7)

This causes N on image 9 to become defined with the value 7.
